I have seen the other posts that discuss this issue, but i'm a newbie at diesels but very competent in mechanical work. I have a 97 CCLB 4x4 with the 7.3. I bought it from a guy who installed an edge eve tune on it on 3 (Extreme). It has straight exhaust and a AFE intake. I have replaced the glow plugs, glowplug relay, fuel pump, and the entire ac system of which still having a problem with the shims in the compressor. I have done all this myself with no problems.

Recently i noticed my truck would take a little longer to start after running it for awhile and thought I had some kind of bad diesel. after a week or so it got better with no notice in lagging cranking time. About 3 days ago it started taking 5-10 sec to crank when warm. No problem starting when cold in the mornings. I got onto all the forums and the suggestion was a bad IPR or ICP Sensor. Both expensive but I want my truck to be right! So I replaced both of them the IPR first with no change and then the ICP today. Truck never left me stranded till today. Eventually started up so I hauled *** home. I checked the level of oil in engine and HPOP, it was good and I changed it about 2 weeks ago with fresh oil filter. I also replaced the seals on the oil cooler then aswell because of a leak.

Today when I got home I plugged in the Edge Evo dohicky and tried to reprogram back to stock to see if that was the problem.. !@#$ now it screws up everything and there sending a reflash unit overnight to fix the error it has now. NO START AT ALL! Freggin unbelievable. I'll get that reflashed tommorrow and discountinue the use of the eve and get a 6 position chip in its place. Anybody want a new Edge Evo it will be here tomorrow?

Anyways. I heard that it could possibly be a bad HPOP or Orings on the injectors but the HPOP is not draining down and the truck runs smooth once started. ANY OTHER IDEAS BEFORE I GO BROKE!

Edge sent the new flash for my truck today. Wow, talked on the phone yesterday with a customer service tech at 3pm and it arrived today at 11am. Georgia to Dallas in a jiffy. So I reflashed to stock but I still dont think I want to run the edge evo again.

Same problem as before the cpm thing. Hard fast cranking after warm but slow to fire. Anybody got any ideas before I go take it to Rockwall Ford and get screwed...

Just spoke to a diesel mechanic and he said to check the battery's when hot and having problem. Took it to Autozone for them to hook it up to there handy dandy machine/computer. 100% batteries. Dangit. If only new batteries would fix this. Well I bought another Cam position sensor which was still under warranty through auto zone from last year when I got the truck. The sensor only has 25000 miles on it. Gonna go change it here in a minute. I'll Get back to ya soon.......

I have been running rotella 15w40 but just switched 2 weeks ago to delo 15w40. I only have the generic one that is in the instrument cluster, and it doesn't really start moving till its started. It has always done that. Any idea where I can get a good one or thoughts on different models. I would like to be able to test all pressures in the truck on my own but don't have the equipment.

There's a thread on here that talks about exactly where to tap for the low oil pressure gauge. The actual port is above the oil filter. As far as specific brands, I have GlowShift gauges, they work great. There are several great brands in the Jegs and Summit catalogs. Bear in mind most of these are only good for the low pressure system. There are gauges that will work on the high pressure side also. I don't know specific brands or where to tap in to check the pressures though there are many people on the board that can make specific recommendations and tell both of us where to tap in.
